I think you've misunderstood their point. They were talking about the superchargers at the cabinet level. They meant that on the traditional superchargers, all 4 groups in the supercharger cabinet are available to either stall. I.e. while the 12 chargers are grouped up into the 4 blocks, either of the stalls has full access to all 12 in the cabinet assuming the paired stall is empty. On the urban supercharger cabinets, the 12 chargers are split into 2 partitions. Each partition having 2 groups of 3 (i.e. 6 chargers). Which is why, even when the paired stall is empty, you're still limited to the 72 kW. It can only be served from it's half of the cabinet. Basically you mostly agreed about what's going on but used different terminology.
